Topic:Disease Management
Disease management in horses encompasses the strategies and practices employed to prevent, control, and treat diseases affecting equine populations. This field involves understanding the etiology, transmission, and clinical presentation of various equine diseases, as well as implementing biosecurity measures and therapeutic interventions. Common diseases in horses include equine influenza, strangles, and equine herpesvirus. Effective disease management relies on accurate diagnosis, vaccination protocols, and the use of antimicrobials and other treatments. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, challenges, and advancements in managing diseases in equine health.
An outbreak of American cutaneous leishmaniasis (Leishmania braziliensis braziliensis) in a periurban area of Rio de Janeiro city, Brazil: clinical and epidemiological studies. From July 1984 to September 1986, 105 cases of American cutaneous leishmaniasis were studied in a locality closely situated to an urbanized area of the city of Rio de Janeiro, Brazil. Settlement in this area was established at least 20 years ago but the first cases were noted six months prior to the beginning of this study. Cases were almost exclusively cutaneous and ulcerated, with one to six months of evolution. Montenegro's skin tests were positive in all cases and anti-Leishmania antibodies were detected by indirect immunofluorescence test in 74.3% of the patients. Parasites were demonstra...
Factors influencing the ingestion of Onchocerca cervicalis microfilariae by Culicoides variipennis (Diptera: Ceratopogonidae). Culicoides variipennis were fed under controlled conditions on two ponies that exhibited seasonal changes in Onchocerca cervicalis microfilarial (mf) skin density and skin distribution. The seasonal changes did not radically affect mf ingestion. Flies were fed on the umbilicus of infected ponies by two methods: individual feeding in consecutive order at the same site, or by mass feeding. Linear regression analysis indicated that ingestion of microfilaria was independent of feeding time and engorged weight. In the individual feeding data, there was a trend toward an increased ingestion of mf as...
Immunoassay detection of drugs in racing horses. VII. Detection of acepromazine in equine urine and blood by ELISA and PCFIA. We have developed and evaluated a one step enzyme-linked immunosorbent assay (ELISA) test and a particle concentration fluorescence immunoassay (PCFIA) test for acepromazine as part of a panel of pre- and post-race tests for illegal medications in racing horses. These tests are rapid, sensitive and economical and development of the tests occurred in less than seven months. The ELISA test detects acepromazine with an I-50 of about 150 pg/ml. In vivo, it readily detects the presence of acepromazine or its metabolites in equine blood and urine from 8 to 72 hours or longer, respectively, after adm...
Experimental chemotherapy in horses infected with benzimidazole-resistant small strongyles. The presence of benzimidazole-resistant strains of equine small strongyles was confirmed in horses at two properties in north west England by a series of faecal egg counts and larval cultures after treatment with mebendazole. A trail formulation of mebendazole in combination with piperazine citrate gave greater reductions in faecal egg counts than mebendazole alone but was much less effective than pyrantel embonate or dichlorvos.
Trauma and the veterinarian. A survey of all American Veterinary Medical Association members in Minnesota and Wisconsin was conducted by questionnaire to document injuries resulting from animal treatment. Of 995 respondents, 64.6% had sustained a major animal-related injury. Seventeen per cent were hospitalized within the last year. Of those hospitalized, 25.3% required a surgical procedure. Hand injuries were most common in a veterinarian's career (52.6% of respondents), followed by trauma to the arms (27.6%), and the head (20.8%). The thorax (8.3%), genitalia (3.9%), and intra-abdominal viscera (2.8%) were injured less ...
African horse sickness in Zimbabwe: 1972 to 1981. During the nine years from October 1972 to September 1981 African horse sickness (AHS) virus was isolated from 23 suspected cases of the disease in Zimbabwe and complement fixation antibody titres indicative of recent infection were detected in a further 49 horses. The 23 isolations belonged to seven of the nine known serotypes of AHS virus. In response to a questionnaire in 1980 the owners of 20% (1,654/8,000) of the horses in Zimbabwe indicated that they had recorded 207 cases of clinically diagnosed AHS with 107 deaths from 1975 to 1980. Fifty-six cases with 50 deaths had occurred in foals ...
[Various aspects of horse sickness]. The aetiology, symptoms, diagnosis and control of African horse sickness are described. Special attention is paid to the introduction and epizootiology of the disease in Spain and its consequences in respect to the international trade of horses.
Validation of a radioimmunoassay for measurement of gastrin in equine serum. A commercial radioimmunoassay kit designed for measuring gastrin in human serum was validated for use with equine serum. This nonextraction, double-antibody procedure uses an antiserum with broad specificity for molecular forms of gastrin. Synthetic human gastrin (G17-I) was added to pooled equine serum, and the observed assay values were compared with the mass added. Recovery was 99 to 115% in the gastrin concentration range of 40 to 640 pg/ml. Dilutions of postprandial serum with serum from fasted horses were assayed, and the inhibition curves were compared with those of the human gastrin ki...
Some aspects of the epidemiology of equine salmonellosis. A survey of 2 horse populations was done to detect the number of asymptomatic faecal excretors of Salmonella sp. 1201 faecal samples from 250 horses hospitalised at the University of Sydney were cultured. Three serotypes, S. typhimurium (4 horses), S. anatum (2) and S. tennessee (1) were isolated from 7 horses (2.8%). None was detected in 75 mares similarly examined at a thoroughbred stud farm. In retrospect, S. typhimurium was also the most common (70%) of the 19 serotypes recovered from 171 horses with clinical salmonellosis seen at Camden, 1969 to 1986. Forty cases occurring since 1983 were...
Nonsystemic causes of the downer cow syndrome. Traditionally, the downer cow has been considered a metabolic problem. This viewpoint cannot account for the pelvic limb predilection of the condition. Whatever the primary cause of recumbency, all recumbent animals are susceptible to pressure damage. The extensive literature on pressure damage in human beings and horses is reviewed. Miscellaneous causes of and contributing factors to bovine recumbency are reviewed. Concepts and details of diagnosis, prevention, management, and therapy are discussed.
A-equi-2 influenza in horses in the Republic of South Africa. In early December 1986 A-equi-2 influenza virus was isolated for the first time in the Republic of South Africa. All horses were susceptible to the highly contagious aerosol-borne orthomyxovirus resulting in widespread outbreaks of equine influenza with typical primary respiratory symptoms. Treatment consisted of rest, anti-inflammatory drugs, antibiotics and good nursing. Future protection can be obtained by vaccination.
